  <p>
    This defines a node template consisting of a top half and a bottom half.
    Each half's text and color are data bound.
    However the size of each node is fixed, so if the text is too long, it will be clipped.
  </p>
  <p>
    The "RoundedTopRectangle" and "RoundedBottomRectangle" figures are defined in
    <a href="../extensions/RoundedRectangles.js">RoundedRectangles.js</a> in the extensions directory.
    See also the <a href="roundedGroups.html" target="_blank">Rounded Groups</a> sample.
